Boneham SF2022EN Slip-fixed Drill Bushing 0.1495 in Id

Product Description

The BONEHAM SF2022EN is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to industry code SF, this bushing features a 0.1495 inch inside diameter (wire size No. 25) and a 5/16 inch body outside diameter, with a length under head of 1-3/8 inches. Constructed from steel and finished with a head configuration, it is installed by machinists, toolmakers, and fixture builders in production and maintenance environments where repeatable hole location accuracy is required. The renewable design allows the bushing to be replaced independently of the jig plate.

This bushing is suited for jig plates, drill fixtures, and tooling assemblies that require a slip-in, fixed-position guide for drill bits, reamers, or other cutting tools. The counterbored head design seats flush or proud depending on fixture geometry. The LS-1 compatible lock screw interface secures the bushing in the liner, making it appropriate for multi-operation fixtures where tooling changes are frequent. Typical applications include metalworking production lines, precision machining shops, and toolroom fixture builds.

Compatibility

Designed for use with LS-1 lock screws and compatible liner bushings in standard slip-fixed drill jig assemblies per industry SF bushing specifications.

Installation Notes

Installation is performed by machinists or toolmakers as part of jig and fixture assembly or maintenance. The slip-fixed bushing is inserted into a pressed liner bushing and secured with an LS-1 lock screw — confirm the liner inside diameter matches the bushing body outside diameter before installation. Always remove all cutting tools and de-energize any associated equipment before servicing fixture components. Do not force the bushing into the liner; a snug slip fit is the intended installation condition.
